Six people were killed Sunday in a gun and car-bomb assault on a police building in the center of the Somali capital that also left seven assailants dead, Security Minister Abdirasak Omar Mohamed said.

At least 13 people were killed on Tuesday in twin bombings near U.N. and African Union buildings adjoining Mogadishu's airport, police said, in what the jihadist Shabaab group claimed as a suicide attack.
